Abstract

A method is provided for using OTDR with a bi-directional optical transmission system that includes first and second terminals (310, 320) interconnected by at least first and second unidirectional optical transmission paths (306, 308) having at least one repeater (314) therein. The method begins by transmitting optical probe signals over the first optical path and receiving over the second optical path returned OTDR signals in which status information concerning the first optical is embodied. The optical probe signals and the returned OTDR signals are transmitted and received, respectively, at time intervals allowing individual spans of this optical path, which are separated by the repeater or repeaters, to be monitored in a sequential manner.
